With regard to Hermanns specifically, are there differences between the genders with regards to keeping them, care, personality, health etc? Sorry if this sounds stupid but I am used to rats, where there are certain goods that males can't eat, females are more prone to mammary tumours and personality-wise boys tend to be more laid back and calm and gis tend to be livelier and into everything. So that's the kind of thing I mean. For a new owner would you recommend one gender over another?
